Preferably the packing or washer 29 should beimpregnated with grease, yand afterthe pistonrod 26 and cylinder head 23, including the bushing 27 andpacking 29 are assembled, these parts should be relatively reciprocated until friction is reduced to a small Referring now to Figure 2 for the view thereof in elevation, and to Figure 3 for the details of construction and assembly,the bottom of the piston rod 26 has secured thereto a piston,'generally designated by the numeral 30. The lower end 'of the piston rod 26 is turned down and screw threaded to form an integral stud 31 and on this stud 31, between a pair of metal washers 32 and .33,

isa leather washer 34, all three of thev washersrv being secured in place by a nut 35, this assemblageconstituting thepiston 30. i

The cylinder 20 and piston .30, Vtogether `with associated parts just described, constitute a pump f for pumping gaseous fuel from the space 12 in. `the receptacle 10 forv a-purpose which will presently appear. 'I'his pump is actuated in one dlrection by finger pressure and in the other direction by'a spring 36 located in the bottom of the cylinder` 20 and pressing against theglower end Aof. thefpiston 30. `According `tocertain features of Y the invention, theupstroke ofthe piston is `the active; stroke, and the portion of the bore ofthe cylinder l20 above thepiston 30 constitutes the.

cylinder spacethat is used for pumping, this space being sealed by the stufllng box 29, already Y described, and by any suitable sealing compound -which is inserted'between' the screwthreads of the cylinder head 23y and thecylinder 20, when saidv cylinder head isscrewed into position as top tothe bottom of the rod.A As the piston is reciprocated air ows back and forth` in thebores.

' Still `referring to Figure V3, the. bore 39` conl .tains'V mechanism adapted to lock the piston i30 `and piston rod 26 in the position shown inthat 1 figure, which represents the closed orinoperative positionof the device. 'I'he upper end of the Through the nut'40 is a bore 41 which is circular in crosssection, and' v'located kin the bore 41 is a pin-42which is square in cross section, thus allowing air to pass kfreely through the bore 41. k'll'hepin42 extends downwardly through the bore 39, the portion therei the device is not in use.`

of below the nut being cylindrical if desired,

anda pistonportion 43 is'formed on the bottom V`"of the pin 42. rIn order Athat `passage of `rair through thebore 39 shall not be prevented by the piston 43, a series o f bores 44 extend `through said piston portion 43. .4 y

Underneath the piston portion 43 and urging vit upwardly is a spring 45 Vthe lower `endof which reacts against theshou'ider 46 constituting the place where the bores 38 and 39 merge.

inattesa;y I, V

The piston portion v43 is prevented from rising beyond the position shown in Figure 3 by means of a press tted washer 47 in the bore 39.

Still referring to Figure 3, a transverse bore 43 is drilled through the piston rod 26 but the drillv is not allowedV to` emerge at the far side, so that alip 49 isformed there, or said lip may be formed` by any other suitable method. A sphere 50 islocated in the bore 48 but cannot emerge therefrom on account of the lip 49, nor can it, when the piston portion 43 is in the position shown in `Figure 3, move into the bore 39. Consequently the sphere 50, when it is held outwardly asinv Figiii'e,` constitutes an abutment engaging the bottom of the cylinder head 23, preventing the pistonrod 26 and piston 30 from rising under the influence of .the spring 36. Whenever, however,

the pin-42 is depressed, the piston `portion 43 is ,lowered below the sphere 50, andthe sphere is then free to move into the bore 39, which it does on account of kthe pressure exerted against it by the reaction of the cylinderhead `23, againstit dueto the pressure of thev spring 36, and the pistony rod 426 and piston 30 rise inthe cylinder 20 under the influence of the,y spring 36. The pin 42 isadaptedto be forcedk down byy finger pressure, and ,when thisis. done the piston and piston rod rise` as described; when it is desired to lock the partsagain in the position shown inthe drawf ingsthe piston may be forced downwardlyyby nger pressure,` exerted against the -nut,40\ andpin 42and the nger slid away from the pinl still under the influence of the spring `45.*forcing the sphere 50 outwardly again and locking the parts withthe piston'30 depressed in the cylinder 20.

12Y for thegas. There is ahole 52 lin the side of the cylinder 20 near ythe top thereof, and whenY holding the nger against-the nut 40 or cover 41, whereupon the piston Iportion 43 springs upwardly .the piston 30 is depressed gaseous fuel is drawn into thecylindery 20. There is another'hole in the upper portion of the cylinder 20 leading to av pipey 54 whichexjtends' upwardly throughthe ,top so" 13er the receptacle 1o, being held in posi-y 'I'he upper end of the pipe,54,\which is bent" over as shown in, Figure 2, `is threaded and a nozzle 56 is secured thereto.v The nozzle56 contains a spring y5,7 which normally holds a ball valve 58 againsta seat 59 on the endof the pipe 54; The spring 57, ball 58 and seat 59, together with the chamber 60 ofthe nozzle56, `thus constitute a check valve allowinggas to be expelled fromr the nozzle 56 but preventing gas or air being sucked through thepipe 54 into the cylinder 20, andpreventing escapeof gas from fthe receptacle 10 when wires 62 of platinum rblacktor ,similar substance are embedded in apiece of metal 63"which is secured to the top wall 13 of the receptacle V10 in any suitable manner', as by forming screw threads on said'pieceof metal 63 and screwing it into a threaded hole 64. In this way the catalytic agent may be readily replaced.

The catalytic agent such as platinum black, when supplied with such gases as a volatilized hydro-carbon, heats up rapidly and glows with a red heat. When th'ewires 62 of catalytic agent are supplied with a draft of volatilized hydrocarbon, they glow and ignite the gas, which btains a supply of oxygen from the surrounding atmosphere. As shown in Figure 2, a snuffer 66 covers the wick 17 when the piston 30 is down, said snuffer 66 being secured, as by soldering, to the cover 41 and pressing against the wick holder 16, thus sealing the fuel in the receptacle 10. When the piston 30 rises under the infiuence of the spring 36, after the latching mechanism has been released, the snuifer 66 rises above the wick 17 and the draft of gas from `the nozzle 56 extends to the wick 17, and when the platinum wires 62 glow red enough to ignite the gas, a flame follows the draft of gas to the wick 17 igniting the wick. Sufficient gas is contained above the upper side of the piston 30 to cause the catalyticl agent 62 to glow hot enough to ignite the draft of gas and thus to ignite the wick l7 as described, so that the depression of the pin 42 and release of the mechanism causes the wick 17 to be lighted.

In order to allow the lighter to be filled a plug 68 is provided which may be conveniently located in the bottom Wall 14 in a seat 69, there being a threaded engagement 70 between the plug and the seat. The seat 69 may be soldered to the bottom wall 14 in order to make ythe connection tight, and preferably a washer 72 of leather is provided between the plug 68 and the seat 69 for the same purpose. A screw slot 73 is desirably provided to screw and unscrew the plug 68, and, as a matter of convenience for the average user, this slot 73 fits a coin, such as a one cent piece.

It will be noted that the inside of the receptacle is completely sealed when the cover 41 is closed except for the entrance A52 into the cylinder 20, but the cylinder is at that time closed by theball 58. When the piston 3 0 is moved downwardly a partial vacuum is created in the cylinder 20 which cannot be .filled through the nozzle 56 on account of the check valve. The liquid fuel in the receptacle 10 rapidly volatilizes and fills the cylinder, so that the piston may be moved up and down despite the absence of any way for air to enter the receptacle 10. This insures the discharge of almost pure gas from the 'nozzle 56 which increases the heat of the wires 62 beyond the temperature which would result were a large proportion of air mixed with the gaseous fuel. In order to reduce the content of air in the receptacle 10 as much as possible the wick holder 16 has alongfdepending portion 16a, as shown in Figure 2, and preferably the wick 17 fits in the wick holder 16 with as tight a. fit as is practicable.

Referring now to lFigure 1, the article when closed has a very nished appearance, none of the operating parts being visible except the pin 42, which projects slightly above the top of the nut 40. The cover 41 may be made to completely enclose the vnozzle 56 and other parts on the top wall 13 ofthe lighter, and the cover 41 thus protects the gas absorption element 62 frominjury. When it 'is desired to operate the lighter the user simply presses downwardly the pin 42 with a finger and allows the cover 41 and other parts to rise. As the parts rise as described, a draft of gaseous fuel is directed against the catalytic agent 62 which ignites near the top of the stroke of the piston 30, and when it ignites a flame follows the path of the escaping gas to the wick 17, and the wick thereafter burns. When a cigar, cigarette or pipe, or other thing which it was desired to light, has been lighted, the user may close the lighter and extinguish the flame by pressing downwardly the cover 41, placing his finger upon the pin 42 so as to allow the ball 50 to be forced inwardly as it passes the cylinder head 23 and bushing 27.

If one upward stroke of the piston does not cause the catalytic agent 62 to glow hot enough to ignite the gas, a second or a third stroke of the piston 30 may be effected by the user, gaseous fuel thus being drawn into the cylinder 20 and expelled therefrom. It will be noted that the pump constituted by the cylinder 20 and piston 30 is a completely operative pump having but a single check valve, which is located in a removable part that is readily accessible. This not only facilitates manufacture of the article and reduces its cost but permits ready inspection of it and easy replacement of the check valve, although its simple construction renders its disarrangement unlikely.

Referring now to Figure 4, a modified construction is shown in which the down stroke of the piston is vthe active stroke that directs the draft of gas against the platinum wires or other catalytic agent 62. The cylinder 20a in the con? struction of Figure 4 is desirably of the same form as the cylinder 20, except that it may be slightly longer, as shown. The piston rod 26a is likewise of similar construction, but the bore 38 is omitted. The piston rod 26a is not shown in cross section because so far as the means for operating the ball lock 50 is concerned such means vmay be constructed substantially as shown in Figure 3. A cylinder head 23a closes the upper end of the cylinder 20a, but in this case no stuffing box 1s provided and the passage through the cylinder head 23a, although desirably square and thus fitting the piston rod 26a, is preferably not a close fit, some tolerance being provided, or else grooves being formed at any place except in the path of the ball 50 to prevent the entrainment of air above the piston 30a. This piston 30a differs from the piston 30 only in being faced in the opposite direction.

In the modified construction a nozzle 56 is provided, as already described, and this nozzle contains the check valve parts already set forth. The pipe 54a, however, leads to the lower portion of the cylinder 20a as clearly shown in Figure 4. The orifice 52a is connected by a pipe 70 to a check valve 71 located in the space 12, this check valve 71 comprising a ball 72, a. spring 73 and a closure 74 screwed on to the end of the pipe 70.

In operating the modified form of lighter shown in Figure 4, the pin 42 (which in this modification need not be square in cross section) is depressed, thus releasing the ball lock 50, whereupon the piston 30a moves upwardly under the influence of the spring 36a. This action draws volatilized-fuel through the check valve 71 into the lower part of the cylinder 20a. When the cover 41 has risen to its extreme limit, the user pushes the cover downward, thus ejecting gas through the nozzle' 56 and causing the wick 17 to be ignited, as already described. The 'parts are shown in igniting position in Figure 5, and after the wick 17 has lighted the cover 41 may be released, whereupon it will move upwardly again well clear of the flame 75, and thereupon such use of the ame may be made as is desired. In order to clear the inside of the cover 41 of vapor which may enter thereinto as the result of the closing of the lighter, vent holes 76 may be provided in the sides thereof, and for general safety purposes such vent holes 76 are desirably also provided in the construction shown in Figure 2.

Certain advantages result from the construction shown in Figure 4, among them being that the user can more completely control the active movement of the pump, and furthermore the danger of the lighter lighting in the pocket of the user is altogether eliminated because the opening movement is the inactive stroke of the pump. It should not be inferred, however, that there is any considerable danger of the lighter of Figure 2 igniting in the pocket, because the lock shown in Figure 3 is reliable. Certain-advantages will follow from the useof the second check valve 71 in connection with the construction shown in Figure 2, and the check valve should in that event be connected to the orifice 52. It is noted, however, that in the construction shown in Figure 2 a certain amount of gaseous fuel may y be forced up through the wick 17 upon upward movement of the piston 30, which notl only makes the wick 17 easier to light but also increases the amount of gas around the catalytic agent 62, and thus makes it glow brighter.

A modified form of nozzle is shown in Figure 7, this nozzle 80 including a catalytic agent in the form of platinum sponge 81. A pipe connection 82 havingfinternal threads 83 at one end and external threads 84 at the other end has a front flange 85 against which bears a spring 86 that presses a ball 87 against the end of the pipe 54 which is shaped to form a seat. The connection is screwed onto the threaded end ,of the pipe 54, as shown, and by means of the threads 84 they nozzle 80 is secured to the connection 82. It is noted that the catalytic agent, such as sponge platinuml, is located partly in the nozzle orifice 88, so that as the sponge heats up it will ignite the gas as it emerges from the nozzle, and an aspiration pipe 90 is preferably used to insure a full supply of oxygen at the point of ignition. When using the form of nozzle shown in Figure 7, which of course may be used with either of the modifications shown in Figures 2 and 4, the wires 62 need not be used. Desirably the nozzle 80 of Figure 7 is located very close to the snuffer cap 66, one side of which is shown in broken lines in Figure 7.

It will thus be seen that there has been provided by this invention an apparatus in which the various objects hereinabove set forth, together with many thoroughly practical advantages, are successfully achieved.

As many possible embodiments may be made of the above invention, and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth, or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.
